Hardware devices that are used to connect computers, printers, fax machines and other electronic devices to a network are called network devices. These devices transfer data in a fast, secure and correct way over same or different networks. Network devices may be inter-network or intra-network.
Repeater –
A repeater operates at the physical layer. Repeater’s job is to regenerate the
signal over the same network before the signal becomes too weak or corrupted so
as to extend the length to which the signal can be transmitted over the same
network.
Repeaters do not amplify the signal. When the signal becomes weak, they copy
the signal bit by bit and regenerate it at the original strength.
It
is a network device used to regenerate or replicate a signal. Repeaters are
used in transmission systems to regenerate analog or digital signals distorted
by transmission loss. Analog repeaters frequently can only amplify the signal
while digital repeaters can reconstruct a signal to near its original quality.
